A suspicious item found at Iowa State University has been determined to be non-explosive.
Captain Darin Van Ryswyk of the University Police Department says the object was a sock pulled over a piece of Styrofoam.:
The item looked suspicious enough that the state fire marshall was called in:
Authorities earlier posted a picture of the item on its Twitter and Facebook pages in an effort to identify the item.
The incident temporarily closed an area near a dining facility and library.
